God has placed salvation within the reach of every single person (Matt. 28:19-20; Titus 2:11). However, the sad truth is that many will not be saved, in fact they cannot be saved (Matt. 22:14). But why is this true? Is it because of some weakness in the gospel (Rom. 1:16)? Is it because God is a respecter of persons (Acts 10:34-35)? Is it because we simply cannot understand God’s will for us (Rom. 1:19-20; Eph. 3:4)? If not these, then why is it that many cannot be saved?  And who are those who cannot be saved?
